.To all whom it may concern.-

Be it known that I, SAMUEL E. Ho PER, a citizen of the United States, residing at Urafton, in'the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in a Combined Boiler Stand and Coupling, of which the following is a specification.

' My invention relates to boiler stands and couplings, and more particularly to upright boilers for the heating or storage of hot water for domestic pur oses. Such boilers are usually placed in cel ars and supported on stands of fixed or standard lengths. When the cel lars are high, the stands sit on the cellar floor or on blocks, and when the cellars are low the stands are buried more or less deep in the cellar-bottoms.

The ordinary stand has a horizontal ring,

on which the vertical bottom flange of the boiler sits, the ring extending inwardly at some considerable distance forming anannular pocket or dead space, bounded above by the bottom of the boiler, outwardly by-the flange thereon, and below by'the flange of the stand. This dead space becomes filled with gases passing off from the burner beneath the boiler and becomes foul and ill-smelling. This space not having a sup ly of air prevents the gas from the burner from becoming entirely consumed, whereby 'a quantity of unburned gas is given ofi in the cellar. The imperfect combustion of the gas due to the said foul-air space or pocket causes alarge quantity of carbon and other materials to be deposited on the bottom of the boiler, thereby preventin a large part of the heat of the burner from eing transmitted to the metal of the boiler-bottom.

My invention aims to improve boilerstands so that they may be adapted to cellars of any height without providing a base therefor above or below the cellar-bottom, and so that the combustion beneath the boiler may be more complete and the aforesaid annular pocket eliminated.

My invent-ion also aims at cheapne'ss of construction, even where the burner is not applied directly to tlfe boiler-bottom.

Referring to the drawings, which forma part of this specification, Figure 1 is an elevation with a port-ion broken away, and Fig. 2, a section of the lower part of a boiler and of my improvement.

On the drawings, 1 designates a vertical UNITE STATE t-l T/iaio ANDQCOU -LINGQ "cylindrical boiler, having the bottom 2 and the usual annular flange 3 extending below the said'bottom. It is this flange 3 that usually sits on the ring of the common stand, the space between the bottom 2, the flange 3, and the ring forming the dead space hereinbefore mentioned. I do away entirely with such a stand and dead space, and mount the boiler in the manner now to be described. I screw into the center of the bottom 2 the fitvertical tube 5 and the two horizontal branch tubes 6 and 7 communicated with the tube 5 at the bottom of the latter. I prefer to secure to one of the branches, as .6, the drainage-cock 8, and in the other I provide a plug 9, which may be removed in order to connect the branch 7 by a pipe leading to a co1lheater or other device. (Not shown.) On the tube 5 I place a collar 5 having an ex: panded upper portion fitting the bottom of the boiler in order to provide an enlarged seat or support for the boiler. The nut 10 maybe used on the tube 5 to screw up against the collar to hold it in place and relieve the screw-threads above it. On the fittings, below the branches 6 and 7, Iprovidea solid projection or lug 11, threaded interiorly to receive the supporting rod or tube or connection 12, whose lower end is screwed or otherwise removably secured in the base block 13 or other base or foundation. Con nections of different lengths may be kept on hand or they may be made as wanted.

14 represents a ring gas-burner surrounding the tube 5 and arranged to direct the heat therefrom against the bottom of the boiler.

It will be seen that I do not have any pocket within the flange '3 to prevent complete combustion and cause the emanation of ill-smelling and noxious gases and to 1ncrease the non-conductive coating on the boiler-bottom. My invention is comparatively cheap and is durable and strong.

If desired, spider arms 5 may be added to the collar, the ends of the arms engaging the bottom of theboiler to aid in supporting 1t.

Having described .my invention, I cla1m 1. In combination, a boiler, a burner beneath the boiler, an outflow-pipe secured in the bottom of the boiler, a collar sleeved on said pipe and seated against the saidbottom, spider-arms on said sleeve extending outwardly and into engagement withthe bottom,'whereby the boiler is supported and the ting 4, which is preferably composed of the Qs e a ca orrof Letters Patentiif. riiateneea rane'a leocw .Applicatiou filed March 1i,1905. s raiiioiztofdi.P
